2 Claims. (Cl. 155-93) This invention relates to new and useful improvements and structural refinements in hassocks, and the principal object of the invention is to provide a hassock which may be quickly and easily adjusted as to height.

This object is achieved by forming the hassock in two sections and providing means for raising and lowering one section relative to the other.

Some of the advantages of the invention reside in its simplicity of construction, in its etficient operation and in its adaptability to economical manufacture.

With the above more important objects and features in view, and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention in its extended position;

Figure 2 is a perspective view thereof in its shortened position;

Figure 3 is a vertical sectional detail, taken substantially in the plane of the line 33 in Figure 1;

Figure 4 is a vertical sectional detail, similar to that shown in Figure 3, but illustrating a modified embodiment of the invention;

Figure 5 is a perspective view of another modified embodiment of the invention;

Figure 6 is a vertical sectional view, taken substantially in the plane of the line 66 in Figure 5;

Figure 7 is a horizontal sectional view, taken substantially in the plane of the line 77 in Figure 6; and

Figure 8 is a sectional view, taken substantially in the plane of the line 8-8 in Figure 6.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, more particularly to Figures 1-3 inclusive, the invention comprises an adjustable hassock which is designated generally by the reference character 10 and embodies in its construction a lower section 12 and an upper section 14.

The lower section 12 includes a substantially circular base 16 provided at the top thereof with an annulus 18 to which is rigidly secured a tubular body member 20, the inner lateral surface of this body member being equipped with screw threads 22.

The upper section 14 comprises a suitable seat 24 provided at the underside thereof with a stepped annulus 26 affording an outer shoulder 28 and inner shoulder 30, and a tubular body member 32 suitably secured to the shoulder 30 and is provided at the outer lateral surface thereof with screw threads 34 which operatively engage the aforementioned threads 22.

Consequently, when the upper section 14 is rotated relative to the lower section 12, the overall height of the hassock may be increased or decreased as desired,

thus varying the height of the seat 24 above the floor accordingly.

A tubular jacket 36 is secured to the shoulder 28 of the annulus 26 and is slidably as well as rotatably telescoped on the body 20 of the lower section 12, so as to obscure the screw threads 34 from view.

In a modified form of the invention shown in the accompanying Figure 4 and designated generally by the reference character 40, the hassock includes upper and lower sections 42, 44 respectively, the upper section 42 including a seat 46 having an annular ring 47 on the underside thereof to which is attached the upper end of a tubular body member 48, while the lower section 44 includes a base 50 and a tubular body member 52.

In this form of the invention, the body member 52 is provided with external screw threads 54 to operatively engage internal screw threads 56 in the body member 48, and the covering jacket 58 is secured to the lower member 44 so as to cover the external screw threads 54.

Referring now to the accompanying Figures 5-8 inclusive, which illustrate another modified form of the invention designated generally by the reference character 60, the lower section 62 of the hassock includes a base 64 and a tubular body member 66, while the upper section 68 includes a seat 70 and a tubular body member 72.

The body member 72 of the upper section 68 is provided therein with a plurality of vertical straps 74 having angulated upper end portions 76 secured to the underside of the seat 68, while horizontal continuations of the lower ends of the straps 74 constitute a cross-shaped framework 78 at the lower end of the body member 72, as is clearly shown in Figures 6 and 7.

The base 64 of lower section 62 is provided with a grooved track 80 having slidably disposed therein a pair of blocks 82 which are provided with screw threaded bores to operatively engage reversely threaded portions 84, 84a of a rotatable actuating shaft 86. This shaft is suitably journaled in the body member 66 and projects outwardly therefrom to carry a hand crank 88 whereby the shaft may be rotated and the blocks 82 drawn together or spread apart as desired.

Pairs of links 90 are pivoted at 92 to the blocks 82 and are also pivoted at 94 to a block 96 secured to the framework 78, whereby the links, the blocks and screw threaded shaft assume the nature of a jack, so that by rotating the crank 88 in one direction or the other, the upper section 68 of the hassock may be raised or lowered with respect to the lower section 62. The body members 66, 72 of the respective sections 62, 68 are slidably telescoped, as is best shown in Figure 6.

It is believed that the advantages and use of the invention will be readily understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

1. An adjustable hassock comprising upper and lower tubular sections, the upper of said sections being telescopingly received within the lower of said sections, a seat closing the upper end of said upper section and a base non-rotatably secured to and closing the lower end of said lower section, cooperating screw threads provided on the inner wall surface of said lower section and the outer wall surface of the upper section for longitu- "Patented Apr. 24, 1956' dinally extending the upper section relative to the lower section, and a jacket depending from said seat and spacedly concentrically surrounding said upper section and concealing the screw threads on the outer surface thereof, the wall of the lower section being received in the space between said jacket and said upper section.

2. An adjustable hassock comprising a stationary lower section including a base having an upstanding tubular, screw threaded body member thereon, an upper section including a seat and a tubular screw threaded body member operatively engaging the body member of the lower section whereby the upper section may be raised or lowered by rotating the same, and a covering sleeve secured to one of said sections and concentrically spacedly surrounding one of said body members, the other body member being telescopingly received in the annular space between said sleeve and said one body member, the external surface of the upper body member be- 'ing threaded and the internal surface of the lower body member being threaded, said sleeve being secured in concentric surrounding relation to the upper body member.
